TEE, MASSACHUSETTS, A. CORPGRATO'I GF SPOOL FOR 'AXIVIINSTER LOOMS.

Application filed Aprilr 53 rIhis inventionfrelates to spools for AX minster looms and it is the principal object of the invention to provide a steel head for the spools having a plurality of ears which are driven into the end of the Wooden bar- .rel of the spool andheld against turning form the ferrule as a collar which may be,`

used to compress the end of the spool barrel so that the Wooden portions thereof may more tightly grip the ears stamped from the steel head.

l/Vith these. and other Vobjects in view vWhiclrivill appear as thedeseription proceeds, my invention resides in the combination and arrangement of parts hereinafter described and set forth in the claims.

*In the acompanying drawings wherein I have shoivn a convenient embodiment of my invention, Y f

Fig. 1 is a front elevation of a tube frame spool applied thereto,

Fig. 2 is an enlarged end elevation taken in the direction of arrow 2, Fig. l,v

Fig. 3 is a vertical longitudinal section on line 3-3 of Fig. 2,

Fig. 4 is a perspective viewv of the ferrnle forming part of my invention, k

Fig. 5 is a view similar to a portion of Fig. 3 but showing .a modified form of the invention, v

Fig. 6 is a vertical section on line 6-6 of Fig. 5, and

Fig. 7 is a detail perspective' view of the tongue-receiving guard used in the modified form of the invention. Referring to the drawings', particularly Figs. 1 to 4, there is shown a tubeframe l() having spool bearing brackets 11 on each end thereof, said bearings supporting the outer ends of spools S carried'by the tube frame. the frame intermediate the ends thereof to support the inner ends of the spools.

The outer end of each spool has a head 14 .formed of pressed steel and having a Web 15 which defines the outer limit'of-the yarn A center bearing 12 is mounted onA 1325. Serial No. 105,280.l

* space, While the inner end of each spool lhas aV steel Vhead .16 defining the inner limit of the yarn'space. Each head 14 is held` in place by a stud 17 passing'throngh the head y and having a shoulder 18`to Vengage the outer surface of thehead, said stud entering the barrel 19 of the spool and being held `therein by pin 20. Stud v`17 .is reduced andk threaded `as at 21 and passes through a Wooden plug 22' passing transversely through the spool barrel.l Ay gudgeon 23 on the outer end of stud 17 is received by bear Prongs 24fare struck Afrom the web 15 and are driven into thej Wooden, barrelv ing 1-1.

19 and said Web alsovhas struck therefrom a tongue 25 Which leaves an opening v26 in said Web.

y Heads 16 are alsoprov-ided With prongsl '27 driven into the barrel and each head has a tongue 28 extending inwardly vtherefron'i Vand forming anopening 29 inthe head 16.

Thebarrel has a slot'SO Whichfis in` alignceives the tongues 25 and 28. ,Heads 16 are lll inentivith the openings 26.'.and 29 and reheld in ,place by studs 3l VWhich havecoinpleV Amentarily formed enlarged endsi'32 having interengaging driving contact With each other. common constructionaiid forms no part of my invention, being similar to the construction set forth inPatent No. 1,067,656.

Vlienthe'spools such as set forth *herein` vare put in the so-called setting' frames .t0 have the variously colored tuft forming yarns Wound thereon, the heads of each spool engage rotating clutches and rotary movement` is transmitted the clutch to the barrel The matt-er thus far described isv of lli tact with thetongues 25 and 28 and in car- 'l ryingont the preferred form of iny invention I provide a ferrule 40=for each end'cf each spool substantially as shown in Fig. 4, With a cylindrical body 41 and 'a recessed guard portion 42.A Prior to assembly of the heads on the spools the ferrules are'driven on the end of the barrels Vwith the' groove'd portions 42 in alignment With the grooves 19.

The studs and heads are then applied, the tongues entering the grooved Vportions i-2 ot the collar and the prongs being driven into In the modilied formr ot my invention shown in Figs. 5, 6 and 7 l omit the terrule construction and provide a guard 50 having lside Walls 5l and a bottom 52 which when assembled will occupy the same position with regard to the head andthe spool as the slotted portion Plot the 'terrule 40.

In bot-h forms of the invention sliding movement ot' the metal ierrule or guard away from the head is prevented by shoulder 53 formed in the barrel'near the ends thereof, and the tongues are in contact with metal Walls which lit the tongues snugly to prevent angular movement oi the heads.

Y `From the foregoing it -ivill be seen that vl have providedv the slotsin Axininster spools With short metallic Walls which cooperate -with the tongues of the heads, said Walls serving not only to guide the 'tongue but also to prevent Vangular movement ot the head With respect to the barrel .of the spool. It is for this reason that the prongs will not ben come loosened and will retain their original holding contact with the Wood of the spool. It will further be noted that in the preferred form ot the invent-ion the hol-ding contact ot the prongs With the Wood is further enhanced by the cylindrical portion of the ferrule. A

Having thus described my invention it will be apparent that changes and modifications may be madetherein by those skilled in the art Without departing from the 4spirit and scope of `the invention, and Ido not Wish to be limited vto the details herein disclosed but what I claim is:

l. ln a spool tor` ixminster looms, a Wooden barrel having a longitudinal groove therein, a sheet metal head, prongs struck up from the head and vdriven into the Wooden barrel, a tongue also struck from the head and extending into the slot ot the barrel, and means providing metallic Walls for the slot in the barrel adjacent the tongue, said tongue engaging'the metallic Walls and said means being held tightly to the barrel.

2. ln a spool tor Axminster looms, a

Wooden barrel having a.V longitudinal groove therein, a sheet metal head, prongs struck up ytrom the, head and driven into the Wooden barrel, a tongue also struck from the head and extending into the slotof the barrel, means providing metallic Walls tor the 4slot in the barrel adjacent the tongue, said tongue engaging the metallic Walls and said means being ield tightly to the barrel, and a stud passing through the head and held in the barrel out of alignment with the tongue to hold the head to the barrel.

3. In a spool tor A Xminster looms, a Wooden barrel having a longitudinal groove therein, a metallic errule surrounding the end o' the Wooden barrel and coniining the end portions thereof, said terrule being formed with a depression in its circumterence which is in alignment With the groove of the barrel, a sheet metal head held to the barrel, prongs struck up from the head and driven into the Wooden barrel to expand the Wood against the lerrule, and a tongue also struck from the head and extending into L that portion of the terrule Which is in alignment with the groove of the barrel, the tongue being thereby `restrained against angular 'movei'nent.

ln testimony whereof I have hereunto affixed my signature.
